SAW ATTACHMENT FOR VEHICLES.

Application filed August 5, 1925. Serial No. 48,411.

To all whom t may conce/1%:

Be it `known that I, FRANK C. HUBBARD, a citizen of the `United States, residing at Dennis, in the county of Parker and State of Texas, have invented new and useful Improvements in Saw Attachments for Vehicles, of which the following is a specification. j This invention relates to improvements in saw attachments for use upon motor vehicles and contemplates the provision of a saw frame adapted to be secured to the vehicle frame and having a saw mounted upon its forward end and receiving its power transmitted by the forward end of the vehicle crank shaft.

.Another object of my invention is the provision of the power transmitting apparatus for the saw in the provision of a shank secured to the crank shaft fan pulley and hai/'ing a socket within its forward end for receiving the saw shaft therein whereby the said crank shaft will move as a unit with the said saw shaft.

' With the above and other objects in view, the inventionfurther includes the following novel features and details of construction, to be hereinafter more fully described,

illustrated in the accompanying drawings and pointed out in the appended claims.

In the drawings Figure 1 is a front elevation of a motor vehicle showing my present invention applied thereto.

Figure 2 is a fragmentary side elevation showing the manner in which my frame is attached to a vehicle.

Figure 8 is a top plan view of the saw and saw frame, perse.

Figure 4 is a sectional view taken through a portion of the vehicle frame and showing the manner in which my invention is attached thereto.

Figure 5 is a fragmentary perspective of the inner end of the saw frame and showing the attaching means thereon.

Figure 6 is a perspective of a fastening element to be secured to the vehicle side bars. v

Figure 7 is a sectional view taken on line 7*7 of Figure 8.

Figure 8 is a sectional view taken on line 8 8 of Figure 7.

Referring to vthe drawings in detail, wherein like characters of reference denote corresponding parts, the reference character 10 indicates a Ford automobile which is shown as having my present invention applied thereto, although I have shown my invention as applied to this particular form of automobile, it is of course understood that I do not limit myself to attaching the saine to any one form of automobile but that minor changes in the form and construction thereof may be made in order that the said invention may be applied to all types of motor vehicles.

The saw frame comprises spaced parallel angle bars 11 having correspondingly shaped cross bar 12 arranged between their inner sides and adjacent the forward ends thereof and which has bearingly mounted as at 13 to the upper side thereof a saw shaft 11i carrying a saw 15 upon its forward end and reduced and squared portions 16 and 17 upon the inner end thereof. Arranged upon the upper sides of the angle bars vl1 and adjacent the inner ends thereof are angle brackets 18 having their angular portions extending upwardly from the outer sides of the angle bars terminating in substantially V-shaped cutout portions 19 upon the upper ends thereof and which are adapted to receive the inner end portions and under sides of the combined lamp brackets and fender braces 20. These brackets 18 are held rigidly positioned against these combined lamp brackets and fender braces 2O through the instrumentality of substantially L-shaped bolts 21 having their offset portions extending over the brackets 18 and adapted to engage the upper sides of the combined lamp brackets and fender supports 2O ,whereby the said angle bars 11 will be rigidly secured to the vehiclev 10. It is my purpose in so associating this frame to the motor vehicle 10 as to take out all vibrations, shocks and the like so that my saw 15 will run evenly and smoothly and in order to accomplish this result the inner ends of the angle bars 11 yinclude slots 22 within their inner ends and which are adapted to receive therein the offset portions 23 of plates 24 secured at their upper ends to the outer sides of the vehicle side bars as clearly illustrated in Figure 2 of the drawings. It will thus be noted that my frame is rigidily supported upon the vehicle l() and all such vibrations, knocks and the like will not occur and interfere with the operations of the saw l5 and its shaft 14.

In order to provide means upon this vehicle lt) for imparting the necessary force, momentum or power to operate the shaft 14- and saw l5, it is necessary to remove the vehicle hand crank and ratchet therefor from the vehicle, not shown, and associate with the motor vehicle crank shaft 25 within the fan pulley 2G, a stub shaft 2T having an enlarged hollow portion 28 upon its inner end for the reception of the fan pulley hub and reduced forward end portion of the crank shaft therein and inn cluding diametrically opposed longitudinally extending slotted portions 29 evtending inwardly frointhe inner ends thereof for the receptionof a pin 30 extending through the hub portions of the fan p'ulley 2G and reduced end portion of the crank shaft 25 and which is ordinarily used for engaging the ratchet upon the inner end of the hand crank, not shown. The forward or outer end of the stub shaft 2T includes a squared socketed portion 3l and within which inserted the inner squared portion 1T provided upon the inner end of the saw shaft la whereby the said shaft 1J,- and saw l5 will be set in motion upon the successive revolutions of the motor vehicle crank shaft 25.

It is further to be noted that owing` to the simplicity of construction and arrangement of parts of the stub shaft and the manner of association thereof with the fan pulley 26 and crank shaft. 25 that the same may be manufactured in great numbers and sold at a very nominal cost and can be attached and removed with little difficulty. An adjustable thrust collar 32 upon the shaft ll will eliminate any thrust or end play and hold the squared end portion 17 of the shaft '1- within the stub shaft 2T and the enlarged socketed portion 28 upon the pulley 2G and crank shaft A platform 33 being arranged upon the under sides and adjacent the outer ends of the angle bars ll for supporting timber and other articles to be cut by the saw l5. The thrust-bearing is clearly illustrated in Figure 3 of the drawings.

The invention is susceptible of various changes in its form7 proportions and minor details of construction, and the right is herein reserved to make such changes as properly fall within the scope of the appended claims. c

Having described my invention what is claimed is:-

l. A saw attachment for use upon motor vehicles comprising a pair of angle bars having elongated longitudinally disposed slots upon their inner ends including a cross bar secured to the inner sides and adjacent. the forward ends thereof, oilset plates secured to the outer sides of the vehicle side bars and receiving the slotted portions of the angle bars thereon, angle brackets secured to the upper sides and adjacent the inner ends of the angle bars and engaging the under sides of the vehicle fender brackets, substantially L-shaped bolts secured to the upper sides of the angle bars and engaging the upper sides of the fender brackets, a saw shaft journaled upon the upper side of the cross bar, and a stub shaft arranged within the vehicle, fan pulley and having its outer end connected to the saw shaft for imparting a source of momentum thereto.

2. A saw attachment for use upon motor vehicles comprising a pair of angle bars supported upon the motor vehicle chassis. a cross bar secured to the inner side and adjacent the forward ends thereof. otlset plates secured to the outer sides of the vehicle side bars for engaging the inner ends of the angle bars bracket. bars arranged upon the angle bars for engagement with the motor vehicle fender lnackets.r bolts arranged upon the upper side of the angle bars and engaging the corresponding portions of the fender brackets, a saw shaft arranged upon the cross bar. and a stub shaft arranged upon the vehicle and associated with the saw shaft for imparting a source of momentum therefor.

ln testimony whereof I affix my signature.

FRANK COBURN HUBBARD.
